CA4HC WALK-BEHIND TROWEL • OPERATION MANUAL — REV. #1 (06/24/20) — PAGE 3
Grinding/cutting/drilling of masonry, concrete, metal and
other materials with silica in their composition may give
off dust or mists containing crystalline silica. Silica is a
basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Repeated and/or
substantial inhalation of airborne crystalline silica can
cause serious or fatal respiratory diseases, including
silicosis.In addition, California and some other
authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such
materials, always follow the respiratory precautions
mentioned above.
WARNING
Grinding/cutting/drilling of masonry, concrete, metal and
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity,or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations.Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials being used.

GENERAL INFORMATION
INTENDED USE
Operate this trowel, its components and tools in accordance
with the manufacturer’s instructions. Use of any other tools
for stated operation is considered contrary to designated
use. The risk of such use lies entirely with the user. The
manufacturer cannot be held liable for damages as a result
of misuse.
TROWEL FAMILIARIZATION
Read all safety instructions carefully. Safety instructions
will be found throughout this manual and on the trowel. Keep
all safety information in good, readable condition. Operators
should be well trained on the operation and maintenance
of the trowel.
This walk-behind trowel is designed for the floating and
finishing of concrete slabs.
Walk around the trowel and take notice of all the major
components (Figure 3)—the engine, blades, steering
handle, gearbox, etc. Make sure there is always oil in the
engine.
Before using your trowel, test it on a flat, watered-down
section of finished concrete that is free of debris and other
objects.
This trial test run will increase your confidence in using the
trowel and will familiarize you with the trowel’s controls. You
will learn how the trowel handles under actual conditions.
Engine
This trowel is equipped with a Honda 3.5 hp (2.6 kW)
gasoline engine (Figure 4). Refer to the engine owner’s
manual for instructions regarding the operation and
maintenance of your engine. If the original engine manual
becomes lost or damaged, please contact your nearest
Multiquip dealer for a replacement.
Drive System
Power is transferred from the engine to the gearbox input
shaft via a V-belt pulley drive system. The pulley engages
a centrifugal clutch.
Gearbox
The gearbox is located beneath the engine and transfers
power to the spider assembly. The gearbox controls the
rotational speed of the trowel and is equipped with two
shafts (input and output).
Spider
The vertical output shaft of the gearbox connects to a cast
hub called the spider. The spider has four arms that extend
outward, to which blades or float pans are attached. As the
gearbox output shaft rotates, so does the spider assembly.
Blades
This trowel comes equipped with four 8-inch wide
combination float/finish blades, equally spaced in a radial
pattern, attached to the vertical rotating shaft by means of
the spider assembly. The blades of the trowel finish concrete
as they are rotated across the surface.
Rotating Guard Ring
This trowel is equipped with a special rotating guard ring. It
is designed to allow the operator to run the unit alongside
walls, pipes and obstructions without marring the surface.
Centrifugal Clutch
This trowel is equipped with a centrifugal clutch. The unit
automatically stops rotating when the handle is released.
